Definitions
- the invention relates to a sensor arrangement for measuring parameters in melts, in particular for measuring the temperature, in particular in metal or cryolite melts having a melting point above 500 ° C, with an upper part and a lower part detachably arranged on the upper part.
- Metal melts can be, for example, steel or iron melts.
- thermocouple is arranged on a support body. This thermocouple protrudes into a container in which the cooling temperature of the melt is measured. Further sensor arrangements for measuring temperatures in melts are known inter alia from DE 103 31 124 B3, wherein glass fibers are used as sensor element. EP 1 034 419 B1 further describes a sensor arrangement which uses a thermocouple similar to DE 44 33 685 C2. Another temperature sensor is known for example from JP 07 229 791 A. Here, a glass fiber is used for the measurement, which receives the radiation from the melt and passes it on to an evaluation unit, in which the temperature is determined from the recorded radiation in a known manner.
- Object of the present invention is to improve the existing devices and to further simplify their reliability.
- the optical fiber preferably used for light conduction and temperature or parameter determination thereof is generally unwound from a roll and passed through the sensor array to its tip.
- the optical fiber has a core made of glass, preferably quartz glass, which is surrounded by a metal sheath, which makes the handling of the glass in the first place possible and, for example, should prevent the unintended breaking of the glass.
- the core is closely surrounded by the metal shell, usually steel shell.
- Such optical fibers are commercially available.
- the optical fiber is guided through the sensor arrangement into the tip of the tube of the lower part, that is, as far as its closed end.
- the sensor assembly is immersed with its immersion end in the melt, in particular, the immersed lower part heats up to an equilibrium temperature with the melt.
- the radiation of the melt is absorbed by the end of the optical fiber and forwarded for evaluation.
- the melt exposed end of the optical fiber is damaged by the effect of temperature, so it can not be used repeatedly for reliable measurements. Therefore, after the measurement, after pulling the sensor assembly out of the melt, the lower part is separated from the upper part.
- the guide tube is pushed out of the upper part by the pressure of the elastic body by a distance which is determined by the arrangement of the guide tube in the upper part, especially by the arrangement of mechanical stops. This distance can be for example 1 - 5 cm.
- the optical fiber, which was originally pushed out of the upper part to the tip of the tube of the lower part is thereby surrounded by the movement path of the guide tube and thereby mechanically stabilized.
- the still outstanding from the guide tube end of the optical fiber can then be broken off in a simple manner, for example by lateral, mechanical action, ie by bending. After that there is an undamaged new one End of the optical fiber available for further measurement.
- a lower part is plugged onto the upper part, the optical fiber is passed through the sensor arrangement through to the tip of the tube of the lower part and the measurement can be carried out.
- the length of the end of the optical fiber to be broken off is determined essentially by the length of the tube of the lower part and the movement of the guide sleeve taking place under the pressure of the elastic body. So that the breaking can take place without substantial deformation of the optical fiber at the breaking point, the inner diameter of the guide tube is on the one hand large enough that a trouble-free feeding of the optical fiber can take place, but on the other hand it is not substantially larger than the outer diameter of the optical fiber, in order to bend the optical fiber at the tip of the guide tube when breaking to prevent as much as possible and to ensure that the cross section of the optical fiber including the metal shell at the breakage is substantially maintained.
- a difference between the two diameters of about 0.5 mm or even less than 0.5 mm has been found to be suitable.
- the feed of the guide tube is, as already described, limited by the concrete construction of the upper part, so that it can be set up so that as little as possible is broken off by the optical fiber in order to reduce costs.
- the sensor arrangement is preferably designed such that the elastic body is designed as a helical spring which can be arranged concentrically around the longitudinal axis of the upper part. This results in a uniform pressure on the guide tube so that it does not tilt and jam.
- the lower part facing away from the end of the guide tube is suitably arranged in a housing which surrounds the elastic element. This effectively prevents damage to the movement mechanism from the outside.
- the front ends of the inside of the housing can determine the spring travel of the elastic body and thus the movement of the guide tube.
- the elastic element preferably within the housing, rests against a collar of the guide tube, so that a uniform pressure acts on the guide tube.
- This collar can be formed at the same time as a circumferential bead with a resilient body facing away from the stop side, which is pressed against a stop surface of the housing of the upper part when the guide tube is in its extended position.
- the housing may thus be formed cylindrically around the longitudinal axis of the upper part, with its lower part facing the end face having an opening for the guide tube through which the optical fiber is guided, wherein the opposite end face has a further opening for the optical fiber.
- the upper part and the lower part are connected to each other by means of a connecting part.
- At least one of the connecting parts prefferably have at least one groove and at least the other connecting part to have at least one bead, one bead of one connecting part and at least one groove of the other connecting part interlocking with one another.

- at least one of the connecting parts is formed of an elastic material.
- One of the connecting parts is expediently tubular at its end facing the other connecting part, wherein the tube may also have a plurality of slots in the longitudinal direction, in order to ensure the elasticity required for fitting and releasing, this tube encompassing the other connecting part at its end facing it ,
- This other, comprising of the tubular connecting part connecting part may also be formed as a tube.
- the connecting part arranged on the lower part of the sensor arrangement has an axially symmetrical cone whose smaller diameter is arranged adjacent to the open end of the tube of the lower part.
- the facing, preferably also conical end of the guide tube engage when connecting the upper part and lower part, so that it is additionally centered and the advancement of the optical fiber is not hindered by steps or the like.
- At least one groove and at least one bead expediently extend around the longitudinal axes of the upper part and the lower part, so that an additional axially symmetrical guidance and a uniform pressure is ensured and the upper part and lower part do not tilt against each other.
- the leadership of the optical fiber can be improved.
- an inlet opening for the melt exhibiting container is arranged, into which projects the closed end of the tube of the lower part. Melt can be taken up in this container to measure the liquidus curve.
- the container is closed at its ends facing away from the lower part and has an inlet opening, which can be arranged pointing laterally or in the direction of the lower part. It may therefore be expedient that the tube of the lower part extends through the inlet opening of the container.
- the container is preferably arranged concentrically around the tube of the lower part and has a closed end at its end remote from the lower part. The end facing the lower part of the sensor arrangement can be open.
- the container is expedient thermally decoupled from the lower part as possible. This can be done in a manner known to those skilled in the art by individual webs, which are arranged around the longitudinal axis of the container or of the lower part and connect the container with the lower part. The smaller the cross-sectional area of the webs as a whole, the better the thermal decoupling.
- the end remote from the lower part of the upper part is arranged on a support tube or an immersion lance, so that the sensor assembly can be easily immersed in the melt and pulled out of it again.
- the housing can be directly connected to the immersion lance or the support tube.
- connectors so-called contacts
- the contacts are adapted to the particular application, so that in addition to a mechanical connection electrical and / or optical contacts can be provided.
